Claims priority, application Norway November 14, 1951 1 Claim. 1

In sheath-knives of usual type an intermediate plate is always provided between the inner ends of the handle and of the knife blade.

The present invention has for its object the formation of said intermediate plate in such a manner that the same may be utilized as a bottle opener and/ or as a tin can opener. This is obtained thereby, that the intermediate plate is extended in two directions, one of said extensions being bent over to form a hook substantially parallel to the back of the knife blade, at a distance therefrom corresponding substantially to the height of a usual crown cap, so that the hook may catch below the edge of a crown cap when the back of the knife blade is positioned against the top surface of the crown cap. Preferably the free edge of the hook is curved, corresponding to the curvature of a bottle neck, where the crown cap is attached.

The other extension of the intermediate plate is provided with a point and an edge. Further a lug is provided at or on the handle at a distance from the edge substantially corresponding to the dimension of the folded edge or bead of a usual container for canned stuff, or a usual can.

The annexed drawing illustrates by way of example an embodiment of the invention, where:

Fig. 1 illustrates a knife used for opening of a bottle having a crown cap.

Fig. 2 is a top view of an intermediate plate.

Fig. 3 is a front view of an intermediate plate, and

Fig. 4 illustrates how the knife may be used for opening of a container for canned stuff.

In the embodiment shown the knife comprises a handle I and a knife blade 2, between which an intermediate plate 3 is located. Said plate is extended in opposite directions.

One extension 4 of the intermediate plate 3 is bent to form a hook 5, the hook portion of which extends in parallel to the back 6 of the knife blade 2.

The distance between the inner surface of the hook 5 to the surface of the knife blade back 6 corresponds substantially to the height of a usual crown cap 1, so that the hook 5 will catch below the cap 1 if the back 6 of the knife blade is placed on the top side of the cap 1, whereby the cap 1 may easily be detached from the bottle.

The other extension 8 of the intermediate plate 3 is provided with an edge 9, preferably pointed as shown at H), which extension forms, together with a 1ug I I, a can opener.

The lug I I is, in the example shown, provided on a plate I2 having a surface area corresponding to that of the end of the handle I.

Between the plate l2 and the intermediate plate 3 is provided a distance member I3, so that the distance between plates 3 and 12 will correspond to the thickness of a usual folded edge or bead of a can I6.

Said lug H is formed by bending over a small flap of the plate 12 and has such shape that it will catch below the lower edge of the bead I4 when the point ID of the edge rests upon the cover l5 (Fig. 4) of the can. If the handle I is pivoted, the point l0 and the edge 9 will out through the cover in usual manner.

I claim:

In a sheath knife including a blade and a handle; bottle cap removing means comprising an elongated plate having a longitudinally extending opening at the center thereof for accommodating the blade shaft so that said plate is disposed between the blade and handle and extends parallel to the major axis of the cross-section of the blade, one end of said plate being bent substantially at right angles for spaced apart and parallel disposition relative to the back edge of the blade so that said bent end of the plate can be engaged under the edge of a crown-type bottle closure with the back edge of the knife blade bearing against the latter for efiecting removal of the bottle closure.
